FIRE-BOX.

SPECIFICATION forming part of Letters Patent No. 761,340, dated May 31, 1904. V

I Application filed December 8, 1903. Serial No. 184,248. (No model.)

To (Ml whom it may concern.-

Be it known that I, ALFRED H. TUCKER, a citizen of the United States, residing at Whiterock, in the county of Huron and State of Michigan, have invented new and useful Improvements in Fire-Boxes, of which the following is a specification.

This invention relates particularly to a grate and fire-box intended to be used for burning coal or coke in a wood-stove, especially an or-' dinary sheet-iron or air-tight stove having no grate suitable for coal. It isalso suitable for use in Wood-burning cook stoves or ranges.

The object of the invention isto produce a device which can be put in or taken out of a stove and which is capable of. adjustment to serve in stovesof various sizes.

In the accompanying drawings, in which the device is illustrated, Figure l is a side View of the device. Fig.2 is an end view thereof. Fig. 8 is a top view, and Fig. 4 is a sectional view-showing the device applied to a stove.

Referring specifically to the drawings, 6 incates the grate of my device, having integral grate-bars 7 and at the ends a series of holes 8, adapted to receive corner-pins 9, which serve to keep the fire-box in proper position on the grate. The fire-box is adjustable in size, as hereinafter explained, and a number of holes are provided, so that the pins may be fixed in the grate in proper position to suit the size of the fire-box, so as to prevent the box from sliding or shifting around, inasmuch as it is not otherwise fastened to the grate. On the underside the grate has a series of steps 10 at the ends, which are serviceable in fitting the grate into stoves having grate-supports at different distances apart.

The fire-box comprises sides Y11 and ends 12 and when in position rests loosely on the grate. The sides are perforated, as shown, for the purposes ofdraft. Each end is formed of two parts or sections, and each section is fastened to or made integral with one of the sides.

The sections lap each other, as indicated at 13,.

and they are slidable with respect to each other for the purpose of making the grate of various widths to fit the stove into which it is to be placed. The parts may conveniently be fixed at adjustment by slot and bolt (indicated at 14) or by other suitable means, and when the parts are assembled the pegs on the sides are located in the holes 8 to suit the size of the fire-box, as heretofore indicated.

In use the grate is placed upon the ordinary cross-bars or jambs 15, such as may be found in a common wood-stove, (indicated at 16,) and the firebox is then adjusted to the proper size and placed upon the grate. This enables 'coal'to be burned in the stove, and inasmuch as the device may be readily removed and inserted it is capable of convenient use on all occasions-where it may be found necessary or desirable to change from wood to coal burning stoves, or vice versa.

What I claim as new, and desire to secure by Letters Patent, is*

The combination with a grate having a series of holes across both ends thereof, of firebox sides having end sections integral therewith, the end sections being lapped over each other and adjustable to vary the width of the fire-box, and pins projecting at the corners of the fire-box sections, into the said holes.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
